碳纤维增强材料(Carbon Fibre Reinforced Poly-mer简称CFRP,具有极好的比强度和比刚度、优秀耐腐蚀性的纤维增强复合材料已广泛用于混凝土结构的粘贴加固工程,形成了纤维增强复合材料补强加固已有混凝土桥梁的新技术,碳纤维加固技术适用于各种结构类型、各种结构部位的加固修补,如梁、板、柱、屋架、桥墩、桥梁、筒体、壳体等结构,要求基层混凝土的强度等级不低于C15即可;另外,砖砌体的某些力学性能也可以用碳纤维进行加固。本文根据国内外关于碳纤维增强复合材料补强加固的工程研究,介绍这一新技术的材料特性、施工方法和技术措施。
Carbon Fiber Reinforced Poly-mer (CFRP), a fiber reinforced composite material with excellent specific and specific stiffness and excellent corrosion resistance, has been widely used in the bonding and reinforcement works of concrete structures to form a fiber reinforced composite filler Strong reinforcement of existing new technology of concrete bridges, carbon fiber reinforcement technology for a variety of types of structures, all kinds of structural reinforcement and repair, such as beams, slabs, columns, roof truss, piers, bridges, cylinders, shells and other structures, requirements In addition, some mechanical properties of brick masonry can also be reinforced with carbon fiber.In this paper, based on the domestic and foreign research on reinforcement and reinforcement of carbon fiber reinforced composites, introduce this new technology The material characteristics, construction methods and technical measures.
